A vintage motorcycle patent drawing renders a classic Harley in precise technical lines against a deep charcoal ground, with three angled views showing the bike's side profile, internal mechanism, and detailed components. The monochromatic blueprint aesthetic captures the mechanical elegance of early 20th-century industrial artwork with crisp linework and handwritten annotations framing the invention. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
